Although he was mostly concerned with the earlier, Dinosaur Park Formation genera Corythosaurus and Lambeosaurus, he suggested that Cheneosaurus would turn out to be composed of juvenile individuals of the contemporaneous Hypacrosaurus altispinus.
In addition, both genera show sperm packet formation and "external fertilization" between male and female motile gametes [ 22].
The two Morrison Formation sauropod genera Diplodocus and Barosaurus had very similar limb bones.
Paranthodon is one of a few genera from the Kirkwood Formation, most of which are unnamed, the only other named genera include the coelurosaurian Nqwebasaurus, and the possible camarasaurid Algoasaurus.
George Olshevsky created the new generic name Jenghizkhan (after Genghis Khan) for Tyrannosaurus bataar in 1995, while also recognizing Tarbosaurus efremovi and Maleevosaurus novojilovi, for a total of three distinct, contemporaneous genera from the Nemegt Formation.
Morphogenetic and osteohistogenetic evaluations of dinosaur genera from the Upper Cretaceous Hell Creek Formation of Montana, North and South Dakota, and equivalent age sediments in adjacent states and Canadian Provinces, are providing evidence that extreme modification of dinosaur skulls occurs when these skulls approach ≥50% adult size in many dinosaur groups, particularly the Marginocephalia.
I see no reason to limit the process of modification... to the formation of genera alone... new families, or orders, are descended from two species of the original genus" [ 7].
The La Venta fauna from Colombia is unique; many of the species and genera described from the Villavieja Formation are known from nowhere else.
So these results indicate that chitinase of R. stolonifer has a broad activity for protoplasts formation among various genera of fungi.
Interestingly, diversification of Pinaceae genera was synchronized with the formation of continents, which began to take on their modern forms during the Cretaceous.
